OD and Nominal Pipe Size Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS). For example, a 1-1/2″ pipe size actually has an outside diameter of 1.9″ NOT 1.5″.
Do plumbers go by ID or OD?
As a rule of thumb, hose uses ID, tubing uses OD, and pipe, while the OD is constant, has ‘nominal’ measurement. The pipe is 1 inch in diameter and has about 8 inch OD.
What does OD inlet mean?
This refers to the diameter of a pipe. Some pipes are measured base on their outside diameter, or O.D. Others are measured by their interior diameter, or I.D.
What does 6mm OD mean?
If you measure the tube from the outside, then you will get a measurement called the O.D. (outside diameter) or, if you measure from the inside, then you get a different number called the I.D. (inside diameter).
How is pipe OD measured?
The outside diameter is from outside edge to outside edge across the pipe. To find it, measure around the circumference of the pipe with flexible measuring tape. Divide the circumference by pi, or about 3.14159.
Is plumbing pipe measured OD?
Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS).

What does OD valve mean?
O.D.: Outside Diameter.
What does NPS stand for in piping?
NPS, or nominal pipe size, is merely the non-metric equivalent in which the diameter is measured in inches (in.). In print, pipe size designations are not followed by an abbreviation of the unit of measurement. For example, a pipe’s diameter might appear as DN 20, or NPS ¾.
Is pipe diameter inside or outside?
All plastic pipe is measured on the outside diameter of the pipe, not the inside diameter. This is because the pipe needs to fit into the socket. The pressure rating of the pipe has no significance.

What size should plumbing pipes be?
In most cases, the main pipeline from the street to your home is either 3/4 or 1 inch in diameter, supply branches use 3/4-inch-diameter pipe, and pipes for individual components are 1/2 inch. Remember that water pressure decreases by a half-pound per square inch for every foot pipes extend above your water supply.
Is copper pipe measured ID or OD?
In the plumbing trade, the size of copper tubing is measured by its outside diameter in millimeters. Common sizes are 15 mm and 22 mm. Other sizes include 18 mm, 28 mm, 35 mm, 42 mm, 54 mm, 66.7 mm, 76.1 mm, and 108 mm outside diameters.
How do you calculate pipe dia?
The equation for pipe diameter is the square root of 4 times the flow rate divided by pi times velocity. For example, given a flow rate of 1,000 inches per second and a velocity of 40 cubic inches per second, the diameter would be the square root of 1000 times 4 divided by 3.14 times 40 or 5.64 inches.
What is the OD of 1/2 galvanized pipe?
1/2-inch galvanized pipe has an OD of about 7 inches, while 1/2-inch PVC has an OD of about 6 inches.

Where is the outside water shut-off valve?
Finding the Water Shut-off Valve Look for a rectangular or round cover that will be near the edge of your property, often between the curb and the sidewalk. Some water main valves are located along an alley, rather than the street. Open the cover to the meter to find the water shut-off valve.
What does FIP and MIP mean in plumbing?
Other Notes About Thread Sizing MPT stands for Male Pipe Thread and MIP stands for Male Iron Pipe which both indicate a male fitting with NPT threads. FPT stands for Female Pipe Threads and FIP stands for Female Iron Pipe which both indicate a female fitting with NPT threads.
